One of my favorites from the very gifted pen of Poul Anderson, Operation Chaos, is being released with its sequel, Operation Luna, as a Kindle Edition on September 18th 2018 and it is now open for pre-order

. Originally published (in book form) in 1971, it depicts an alternate Earth where magic works along with technology and follows the lives (sequence of short stories) of Steve & Ginny, werewolf & witch respectively, as they fight Satan as an embodiment of Chaos. I am uncertain of when Mr Anderson started this series but I see similarities with Robert Heinlein's 1940 "Magic Inc." where magic is another tool along with technology.
This is one of the books that I am always remembering and desiring in ebook form as I cannot find my old paperback copy. Like some others, notably Zelazny's "Lord of Light" and Zenna Henderson's 'The People' series, there appear to be barriers in getting these deceased authors works into the more available ebook formats

. Thus I am always delighted when one of these makes it over to the reading side.
Do not get me wrong, there is a delight in sitting and reading a dead-tree book at leisure with an appropriate beverage at hand. That being said, having a book in eprint makes access and usability gains that I find quite nice as well. Add to that the ability to NOT LOSE THE BOOK (moves, fires, loans to 'friends'

etc.) and a very form-friendly airline carry-on, means good things to me!
